Traveling-Wave Wide-Band Microstrip Antennas

Microstrip antennas that can be made to perform well over relatively wide frequency ranges but are mechanically and electrically simpler than prior such antennas have been invented. These antennas are designed to support traveling waves, in contradistinction to being designed traditionally to support standing waves. The exploitation of traveling waves to enable wideband operation is not new in itself; the novelty of the present invention lies in the electrical and mechanical antenna configuration for supporting traveling waves.

Spintronic Effects in Semiconductor Nanostructures

Progress has been made in calculation of spintronic effects in semiconductor nanostructures. The calculations contribute to the body of theoretical knowledge complementing recent experimental advances in generating, transporting, and detecting coherent spin-polarized populations of electron and nuclear spins in semiconductors. The experimental advances have demonstrated that spintronic effects could be harnessed as the basis of novel nanoscale devices. Theoretical advances are needed to understand and extend the experimental advances by enabling inference of previously unknown phenomena from results of experiments and incorporation of these phenomena into realistic models of operation and performance of spintronic devices, including devices that could be used in quantum computation.

Multi-Cores: The Gateway to Next-Gen SBCs and Blades

With the introduction of Intel Core microarchitecture into embedded systems, history could very well repeat itself. The company that invented the microprocessor in 1971 and created the very first micro-controller in 1976 is about to revolutionize the embedded space once again. By bringing the power of parallel processing to embedded developers in an open-standards-based building block architecture, Intel is hoping to break down the cost barriers while taking embedded systems performance to new levels that once were reserved only for expensive computer systems specifically designed for symmetric multiprocessing (SMP), while also accomplishing unrivaled levels of efficiency.

How to Design an Embedded RDBMS Search

As the cost of micro-disk and NAND Flash continue to drop, devices are storing more and more data. It is common now for a person's MP3 player to have more storage than their laptop. But this increase in storage capacity has not been matched with advances in the user interface. Typically, users still wrestle with a folder-based interface to find the data they want, searching by a few vendor-defined categories such as artist, album, and genre. But a new class of embedded database manage- ment systems (DBMS) is emerging to allow end users to search the way people think, rather than in this stat- ic manner. With a RAM footprint ranging from a few tens to a few hundred kilobytes, these products enable developers to deliver this sophisti- cated search on mobile devices. So how do they work? How do you write an embedded application to use a relational DBMS (RDBMS)? While there are a few kinds of DBMS, the relational model has tri- umphed over all the others, largely because it abstracts the data struc- tures so that applications don't have to know them. A relational database management system offers a standard, high-level query language that allows access to data by content, not by pointer or location and offset.

Beamforming System Eases Crowded Wireless Spectrum

Beamforming is critical to enable initiatives by the U.S. Federal Communications Commission (FCC) to increase spectrum capacity and provide additional cellular service and coverage through satellite and terrestrial systems. The key technology for this application is beamforming, which electronically steers data streams to and from a satellite via a combination of an array of antennas on the satellite and very sophisticated, ground-based computational engines.

SOA in Practice: Model-Driven Repositories Fill the Gap Between Concept and Implementation

In the past, network-based applications were pretty simple. A networked server ran a monolithic application that users accessed via a basic GUI (graphical user interface). Today, organizations struggle to develop feature-rich, network-based applications while also facing business pressure to minimize timescales, maximize quality, and work with legacy systems hosted on different platforms.
